LAS VEGAS -- About 60 people were treated for injuries, most after falling during a stampede leaving the arena following Saturday's Floyd Mayweather-Marcos Maidana fight, Las Vegas Metro Police Department said.

Police confirmed there was a loud bang or pop that led hundreds of people just outside the arena -- but inside MGM Grand, and just outside the media room -- to race for safety.

Twenty-four people were taken to local hospitals for treatment, according to Clark County Fire Department.

Hundreds of people stormed the media room shortly after the fight ended to escape the mass of people. Police and security officials briefly locked and barracaded the room so no one could enter or exit.

There was no evidence of gunfire, police said, and fans attending the fight had to clear metal detectors for entry.
